Abstract
Definitions in health are important for a variety of reasons including helping to determine the appropriate allocation of resources. Given the burgeoning costs of health care in many countries it is critical to be clear about which people need what services at any point in time. With changing definitions of unhealthy cholesterol levels, for example, 13 million then 36 million then 40 million Americans were considered to be in need of treatment.
